Khuôn làm đá viên cho bình nước

The spears slide straight out of the tray without any twisting, and they drop right into my insulated bottle’s narrow opening. My water stays icy for hours now, which is exactly what I needed for long workdays.

Finally, a tray that actually makes ice that fits my bottle opening instead of chunky cubes that jam at the neck. The spears slide right down and keep my water cold for my whole afternoon commute, no splashing or jostling loose. It's become a daily habit I didn't know I needed.

The spears fit snugly into my narrow bottle neck without any fuss, and the silicone tray pops them out cleanly every single time. My water stays biting cold through a whole afternoon hike, which is exactly what I needed for daily use.
